Spray bath



United States Patent poration of New York Filed July 12, 1960, Ser. No.42,386 2 Claims. (Cl. 4-148) This invention relates to a spray bath andwhile not limited thereto, the same has particular reference to a spraybath for dolls.

An object of the invention is to provide a bath tub and a sprayattachment for continuously recirculating water from the tub for thedischarge thereof into the tub in the form of a spray.

A further object of the invention is to provide a motor driven impellerlocated below the bottom of the bath \tub for gravitationally receivinga stream of Water from the tub which is forced through a spray headmounted on the free end of a flexible hose adapted to be directeddownwardly into the tub.

Still another object of the invention is to provide an impeller having atop wall and vanes connected therewith and extending outwardly in offsetrelation from the center of the impeller and with adjacent vanesdisposed in substantially right angular relation.

With the foregoing and other objects in View, reference is now made tothe following specification and accompanying drawings in which thepreferred embodiment of the invention is illustrated.

In the drawings:

FIG. 1 is a perspective view of a dolls bath tub and spray attachmenttherefor constructed in accordance with the invention.

FIG. 2 is an enlarged fragmentary sectional view taken approximately online 22 of FIG. 1.

FIG. 3 is a fragmentary view in elevation at one end of the tub.

FIG 4 is an enlarged fragmentary sectional view taken approximately online 4-4 of FIG. 3.

Referring to the drawings, the spray bath includes a bath tub and aspray attachment 11 affixed to the tub at one end thereof.

The tub 10 is preferably of integral formation and includes arectangular shaped receptacle having a bottom outlet 12 adjacent one endthereof and with a rim 13 extending about the upper edge of thereceptacle. The n'm 1'3 is formed with a downturned flange '14 anddepressed trays 15 are provided in the forward end of the rim 13 forreceiving soap or other articles adapted for use during the bathing andspraying operation. The wall between the receptacle and the trays 15 isrecessed as at 16 for draining water from the trays into the tub.

The spray attachment 11 is aifixed to the tub below the forward end ofthe rim and includes a cylindrical housing 18 in which a direct currentmotor 19 is arranged in upright relation with the armature shaft 20thereof journaled for rotation in a partition wall 21 and in a removabletop wall 22. The armature shaft protrudes through the partition wall 21and has an impeller or pump 23 affixed to the protruding end thereof.The impeller is mounted for rotation within a cylindrical chamber 24located in the lower part of the housing below the partition wall 21.The impeller chamber 24 has an inlet opening 25 extending centrallythrough the bottom wall 26 of the housing and an outlet opening 27 inthe side wall thereof. A conduit 29 is affixed to the bottom wall of thehousing and is connected with the bottom outlet 12 of the tub forgravitationally receiving a flow of water from the tub and for directingthe same upwardly into the impeller chamber 24 through the inlet opening25. The impeller chamber 24 is disposed Patented Jan. 9, 1962 2 belowthe bottom wall of the tub whereby water will drain from the tub so asto fill the impeller chamber at all times when there is a ilow of waterinto the tub. A

flexible hose 30 having a spray nozzle 31 on the free end thereofisconnected with the housing at the outlet opening 27 for receiving a flowof water from the impeller chamber which is discharged through the spraynozzle. 7

Affixed to the housing 18 is a container 32 having a removable cover 33closing the outer side thereof in which is arranged a plurality of drycell storage batteries 34 disposed in end to end relation with theendmost batteries in electrical contact with spring terminals 35 and 36affixed to the side wall 37 of the container.

The motor 19 is in circuit with the batteries '34 by conductor wires 38and 39. The conductor wire 38 is connected with the spring terminal 35and the conductor wire 39 is connected with a contact 40 carried by theside wall 37 adjacent the spring terminal 36. A switch 41 is pivoted tothe spring terminal 36 with the outer end 42 thereof projecting from thecontainer and the inner end thereof being adapted to be moved into andout of engagement with the contact 40 for making and breaking thecircuit with the motor by manipulating the projecting end 42 of theswitch.

The impeller 23 is rotated in a clockwise direction by the motor 19 andfunctions to effect a continuous discharge of water through the flexiblehose 30 and into the tub. The water is gravitationally fed into theimpeller chamber from the tub. Thus, the water will be continuouslyrecirculated from the tub and through the spray head. The impeller 23 isconstructed for receiving an upward flow of water and for the dischargethereof laterally and includes a top wall 44 of annular formation fromwhich depends a plurality of vanes 45. The vanes are four in number andemanate from a central hub 46 in offset relation with reference to thecenter thereof and with adjacent vanes disposed in substantially rightangular relation. The vanes extend below the hub so as to provide aspace between the inner edges 47 thereof for the flow of water betweenthe van-es upwardly from the inlet opening 25. A filter 48 is arrangedin the conduit 29 for filtering the water draining from the tub.

The spray attachment 11 constitutes a unit with the parts thereofconnected together and aflixed to the tub 10 and rim 1'3 by any desiredmeans such as by the apertured extensions 49 and 51 through which extendlugs 50 and 52 with nuts secured on the outer ends of said lugs.

The tub is provided with feet 53 for spacing the recep tacle from asupporting surface and to provide a clearance for the lower portion ofthe spray attachment.

While the preferred form of the invention is shown and described herein,it it to be understood that the same is not so limited but shall coverand include any and all modifications of the invention which fall withinthe purview thereof.

What is claimed is:

1. In a device of the character described, a bath tub open at the topand having a bottom wall provided with a drain opening, a spray deviceincluding a housing affixed to said tub exteriorly thereof and having apump chamber at one end of said housing, a direct current motor arrangedin said housing with the armature shaft her having inlet and outletopenings, a conduit connected with the inlet of said pump chamber andwith the drain outlet of the tub with the pump chamber disposed at alower elevation than the bototm wall of the tub for gravationallyreceiving the flow of water from the tub through said drain outlet, aflexible conduit connected with the outlet of said pump chamber andhaving a spray nozzle on the free end thereof, said flexible conduitbeing adapted to be manually held and moved for spraying a doll whendisposed in the tub, electric storage means carried by said tub, andelectrical circuit means connecting said storage means with said motorfor driving the same and including a switch arranged in said circuitmeans for placing said motor in and out of operation.

2. In a device of the character described as set forth in claim 1 inwhich the tub is provided with a rim extending outwardly at one endthereof adjacent the top and the housing and the motor and pumpcontained therein and the electric storage means are supported under therim.
